DETAILED DESCRIPTION 1. Definitions

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Methods and materials are described herein for use in the present disclosure; other, suitable methods and materials known in the art can also be used. The materials, methods, and examples are illustrative only and not intended to be limiting. All publications, patent applications, patents, sequences, database entries, and other references mentioned herein are incorporated by reference in their entirety. In case of conflict, the present specification, including definitions, will control.

The term “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” includes any and all solvents, co-solvents, complexing agents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, which are not biologically or otherwise undesirable. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in the therapeutic formulations is contemplated. Supplementary active ingredients can also be incorporated into the formulations. In addition, various excipients, such as are commonly used in the art, can be included. These and other such compounds are described in the literature, e.g., in the Merck Index, Merck & Company, Rahway, N.J. Considerations for the inclusion of various components in pharmaceutical compositions are described, e.g., in Gilman et al. (Eds.) (2010); Goodman and Gilman's: The Pharmacological Basis of Therapeutics, 12th Ed., The McGraw-Hill Companies.

As used herein, a “single-dose” refers to a sterile formulation that is packaged in a container for parenteral administration (injection or infusion). A single-dose formulation is designed for use with a single patient as a single injection/infusion. Examples of containers for use with single-dose formulations include vials, ampules, bottles, and syringes.

“Ready-to-use,” as used herein, refers to a formulation that does not require constitution or dilution with a prescribed amount of diluent, e.g., water for injection or other suitable diluent, before use by the designated route. For example, a formulation in a vial, of the desired concentration, that only needs to be drawn up into a syringe.

The term “polymorph,” as used herein, refers to crystals of the same molecule having different physical properties as a result of the order of the molecules in the crystal lattice. Polymorphs of a single compound have one or more different chemical, physical, mechanical, electrical, thermodynamic, and/or biological properties from each other. Differences in physical properties exhibited by polymorphs can affect pharmaceutical parameters such as storage stability, compressibility, density (important in composition and product manufacturing), dissolution rates (an important factor in determining bio-availability), solubility, melting point, chemical stability, physical stability, powder flowability, water sorption, compaction, and particle morphology. Differences in stability can result from changes in chemical reactivity (e.g. differential oxidation, such that a dosage form discolors more rapidly when comprised of one polymorph than when comprised of another polymorph) or mechanical changes (e.g., crystal changes on storage as a kinetically favored polymorph converts to a thermodynamically more stable polymorph) or both (e.g., one polymorph is more hygroscopic than the other). As a result of solubility/dissolution differences, some transitions affect potency and/or toxicity. In addition, the physical properties of the crystal may be important in processing; for example, one polymorph might be more likely to form solvates or might be difficult to filter and wash free of impurities (i.e., particle shape and size distribution might be different between one polymorph relative to the other). “Polymorph” does not include amorphous forms of the compound. As used herein, “amorphous” refers to a non-crystalline form of a compound which may be a solid state form of the compound or a solubilized form of the compound. For example, “amorphous” refers to a compound without a regularly repeating arrangement of molecules or external face planes.

The term “anhydrous,” as used herein, refers to a crystal form of the compound of Formula (I) that has 1% or less by weight water. For example, 0.5% or less, 0.25% or less, or 0.1% or less by weight water.

The term “solvate” as used herein refers to a crystalline form of a compound of Formula (I), such as a polymorph form of the compound, where the crystal lattice comprises one or more solvents of crystallization.

The term “non-stoichiometric hydrate” refers to a crystalline form of a compound of Formula I that comprises water, but wherein variations in the water content do not cause significant changes to the crystal structure. In some embodiments, a non-stoichiometric hydrate can refer to a crystalline form of a compound of Formula I that has channels or networks throughout the crystal structure into which water molecules can diffuse. During drying of non-stoichiometric hydrates, a considerable proportion of water can be removed without significantly disturbing the crystal network, and the crystals can subsequently rehydrate to give the initial non-stoichiometric hydrated crystalline form. Unlike stoichiometric hydrates, the dehydration and rehydration of non-stoichiometric hydrates is not accompanied by a phase transition, and thus all hydration states of a non-stoichiometric hydrate represent the same crystal form. In some embodiments, a non-stoichiometric hydrate can have up to about 20% by weight water, such as, about 20%, about 19%, about 18%, about 17%, about 16%, about 15%, about 14%, about 13%, about 12%, about 11%, about 10%, about 9%, about 8%, about 7%, about 6%, about 5%, about 4%, about 3%, about 2%, or greater than 1% water by weight. In some embodiments, a non-stoichiometric hydrate can have between 1% and about 20% by weight water, such as between 1% and about 5%, 1% and about 10%, 1% and about 15%, about 2% and about 5%, about 2% and about 10%, about 2% and about 15%, about 2% and about 20%, about 5% and about 10%, about 5% and about 15%, about 5% and about 20%, about 10% and about 15%, about 10% and about 20%, or about 15% and about 20% by weight water.

In some embodiments the % water by weight in a crystal form, such as a non-stoichiometric or stoichiometric hydrate, is determined by the Karl Fischer titration method. In some embodiments, the crystal form is dried prior to Karl Fischer titration.

“Purity,” when used in reference to a composition including a polymorph of a compound of Formula (I), refers to the percentage of one specific polymorph form relative to another polymorph form or an amorphous form of a compound of Formula (I) in the referenced composition. For example, a composition comprising polymorph Form 1 having a purity of 90% would comprise 90 weight parts Form 1 and 10 weight parts of other polymorph and/or amorphous forms of the compound of Formula (I).

As used herein, a compound or composition is “substantially free of” one or more other components if the compound or composition contains no significant amount of such other components. Such components can include starting materials, residual solvents, or any other impurities that can result from the preparation of and/or isolation of the compounds and compositions provided herein. In some embodiments, a polymorph form provided herein is substantially free of other polymorph forms. In some embodiments, a particular polymorph of the compound of Formula (I) is “substantially free” of other polymorphs if the particular polymorph constitutes at least about 95% by weight of the compound of Formula (I) present. In some embodiments, a particular polymorph of the compound of Formula (I) is “substantially free” of other polymorphs if the particular polymorph constitutes at least about 97%, about 98%, about 99%, or about 99.5% by weight of the compound of Formula (I) present. In certain embodiments, a particular polymorph of the compound of Formula (I) is “substantially free” of water if the amount of water constitutes no more than about 2%, about 1%, or about 0.5% by weight of the polymorph.

As used herein, a compound is “substantially present” as a given polymorph if at least about 50% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 60% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 70% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 80% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 90% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 95% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 96% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 97% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 98% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 99% by weight of the compound is in the form of that polymorph. In some embodiments, at least about 99.5% by weight of the compound is in the form of that polymorph.

“Room temperature” or “RT” refers to the ambient temperature of a typical laboratory, which is typically around 25° C.

The term “administration” or “administering” refers to a method of giving a dosage of a compound or pharmaceutical formulation to a vertebrate or invertebrate, including a mammal, a bird, a fish, or an amphibian. The preferred method of administration can vary depending on various factors, e.g., the components of the pharmaceutical formulation, the site of the disease, and the severity of the disease.

“Subject,” as used herein, means a human or a non-human mammal, e.g., a dog, a cat, a mouse, a rat, a cow, a sheep, a pig, a goat, a non-human primate or a bird, e.g., a chicken, as well as any other vertebrate or invertebrate. In some embodiments, the subject is a human.

As used herein, “therapeutically effective amount” is an amount of the formulation provided herein comprising a compound of Formula (I), or salt or amorphous or polymorph form thereof, which is sufficient to achieve the desired effect and can vary according to the nature and severity of the disease condition, and the potency of the compound. A therapeutic effect is the relief, to some extent, of one or more of the symptoms of the disease, and can include curing a disease. “Curing” means that the symptoms of active disease are eliminated. However, certain long-term or permanent effects of the disease can exist even after a cure is obtained (such as, e.g., extensive tissue damage).

“Treat,” “treatment,” or “treating,” as used herein, refers to administering a compound or pharmaceutical formulation as provided herein for therapeutic purposes. The term “therapeutic treatment” refers to administering treatment to a patient already suffering from a disease, thus causing a therapeutically beneficial effect, such as ameliorating existing symptoms, preventing additional symptoms, ameliorating the underlying metabolic causes of symptoms, postponing or preventing the further development of a disorder and/or reducing the severity of symptoms that will or are expected to develop.

Single-dose, ready-to-use formulations containing either 0.015 mg/mL, 0.025 mg/mL or 0.115 mg/mL of polymorph Form 1 of the compound of Formula (I) were prepared. The compound of Formula (I) was prepared according to the process provided in US 2013/0267495, incorporated herein by reference in its entirety. The polymorph of Form 1 was prepared as described herein.

For a 0.015 mg/mL Formulation:

Water, sodium carboxymethylcellulose (CMC) (5.55 g/kg), polysorbate 80 (0.50 g/kg), sodium phosphate monobasic monohydrate (0.268 g/kg), sodium phosphate dibasic heptahydrate (2.44 g/kg), and sodium chloride (9.11 g/kg) were added to a 300 L first tank. The aqueous solution in the first tank was then filtered through a 0.2 μm polyethersulfone (PES) filter into a second tank, where it was bulk sterilized. 0.15 g/kg of polymorph Form 1 of the compound of Formula (I), water for injection, and 0.5 g/kg polysorbate 80 were added to a 30 L third tank to form a slurry containing 15 μg/mL of the compound of Formula (I). The slurry was sterilized by overhead steam pressure, then added to the second tank containing the aqueous solution. The slurry was homogenized at 30 Hz and manufactured using principles of overkill cycle (F₀≥30). The mixture was aseptically mixed with sterile diluent to form a suspension with a concentration of 0.015 mg/mL of the compound of Formula (I). The bulk solution temperature was maintained at 250° F. as monitored by bottom TC and overhead pressure was maintained greater than the steam pressure introduced in the tank jacket (˜5 psi). To maintain overhead pressure during bleeding of the top valve next to the mixer to monitor TC above the tank, steam was introduced via the air filter into the tank to maintain pressure and high temperature. The steam pressure was monitored and bulk sterilization performed. The suspension was then aseptically filled using a Weiler 624 BFS machine into 3 mL polypropylene vials, with a target volume of 2.5 mL and a final concentration of 0.015 mg/mL of the compound of Formula (I). Each vial contained 0.03 mg of Form 1 of the compound of Formula (I) in 2 mL phosphate buffered saline. The vials were labeled and packaged.

The slurry was sterilized by overhead steam pressure, then added to the second tank containing the aqueous solution. The slurry was homogenized at 30 Hz and manufactured using principles of overkill cycle (F₀≥30). The mixture was aseptically mixed with sterile diluent to form a suspension with a concentration of 0.035 mg/mL of the compound of Formula (I). The bulk solution temperature was maintained at 250° F. as monitored by bottom TC and overhead pressure was maintained greater than the steam pressure introduced in the tank jacket (˜>5 psi). To maintain overhead pressure during bleeding of the top valve next to the mixer to monitor TC above the tank, steam was introduced via the air filter into the tank to maintain pressure and high temperature. The steam pressure was monitored and bulk sterilization performed. The suspension was then aseptically filled using a Weiler 624 BFS machine into 3 mL polypropylene vials, with a target volume of 2.5 mL and a final concentration of 0.035 mg/mL of the compound of Formula (I). Each vial contained 0.07 mg of Form 1 of the compound of Formula (I) in 2 mL phosphate buffered saline. The vials were labeled and packaged.

The slurry was homogenized at 30 Hz and manufactured using principles of overkill cycle (F₀≥30). The mixture was aseptically mixed with sterile diluent to form a suspension with a concentration of 0.075 mg/mL of the compound of Formula (I). The bulk solution temperature was maintained at 250° F. as monitored by bottom TC and overhead pressure was maintained greater than the steam pressure introduced in the tank jacket (˜>5 psi).

Example 2: Polymorph Screen

A polymorph form of the compound of Formula (I) was used in the ready-to-use formulations described in Example 1, above. A polymorph screen was performed on the compound of Formula (I) to determine solubility, polymorphism, and thermodynamic stability.

A. Analysis of the Starting Solid

X-ray powder diffraction (XRD), differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA) scans of the starting solid compound of Formula (I) indicated that the starting solid was a crystalline material and was a mixture of Form 1 and a non-stoichiometric or stoichiometric hydrate of Form 1 having between 1% and about 20% by weight water. According to the DSC scan (FIG. 12B), the solid showed a wide endotherm between 50° C.-100° C.; it also showed a sharp exotherm at 284° C.; and the solid eventually melted at 364° C. According to the TGA scan (FIG. 12C), a 1.4% weight loss was observed before 100° C.

The solubility of the starting solid was measured by the gravimetric method and indicated that the compound had low solubility at RT and at 50° C. in all solvents tested except DMF and DMSO. Results from the solubility data test at RT and at 50° C. are shown in Table 3.

Reslurry experiments in various solvents were performed. Approximately 30-80 mg of the starting solid (a non-stoichiometric or stoichiometric hydrate of Form 1 having between 1% and about 20% by weight water) was slurried in 39 different solvents (pure and binary solvents; the ratio of organic solvent/water (V/V) was 95%/5%) at RT and 50° C. for 5 days. Three solvates, one hydrate, and eleven non-solvated forms were identified. A “*” after a particular Form, e.g., Form 2*, indicates that the forms had similar XRD scans with minor differences and were considered to belong to the same class. Generally, the identified forms showed multiple endotherms/exotherms on differential scanning calorimetry (DSC) scans; Form 9 showed a single endotherm. XRD of both wet and dry samples were scanned (FIG. 12A (dry sample)). The data is shown in Tables 4 and 5 below.

The slurry experiments identified 3 solvated forms from wet samples (Solvates 1, 2, and 3); 2 non-stoichiometric hydrates of Form 1 (Forms 12 and 13); and 11 non-solvated forms (Forms 1-11). In some instances, similar XRD scans with minor differences were obtained. These were considered to be part of the same class (e.g., the same form). For example, XRD scans of Form 2 and Form 2* were similar and were considered to belong to the same class. The solvated forms were obtained from wet sample analysis; after drying, the sample indicated a different XRD.

Solvate 1 was obtained from acetone at RT, and after drying, a low crystallinity solid was generated. Solvate 2 was obtained from acetone (at RT) and acetone/water (at RT), and after drying, Form 4** was generated. Solvate 3 was obtained from EtOH/water at RT, and after drying, Form 2 was generated.

B. Form 1

The experiments that generated Form 1 are shown in Table 6, below. Form 1 was generally obtained from drying of Form 13 or Form 12. Form 1 may be considered as a dehydrated hydrate. Reslurry in many binary solvents (with 5% water) generated Form 1. Purity of the residual solid was 98.9%. KF of Form 1 (one sample) solid was 5.8%; residual MeOH of Form 1 solid was 0.01%. A TGA scan of fully dried Form 1 solid was performed (FIG. 1C). A 0.33% weight loss was observed before 100° C.

Form 1 showed sharp crystalline peaks on the XRD scan (FIG. 1A). The XRD peaks of Form 1 are shown in Table 7, below. According to the DSC scan (FIG. 1B), the solid showed a wide endotherm between 50-100° C.; it showed a sharp exotherm at 281° C.; and the melting point was 363° C. Form 1 has a primitive orthorhombic crystal structure with the approximate dimensions: a [Å]=29.062, b [Å]=23.945, c [Å]=7.245 and an approximate volume cell of [Å³/cell]=5,041.7 and a space group defined as Pbca (61).

The Form 1 solid was dried at 75° C. under vacuum overnight, and XRD, DSC, and TGA scans were performed. Comparison of the first and the second XRD scans (after drying at 75° C. under vacuum overnight), showed no change. However, the DSC scans indicated the absence of endotherm. The loss of the early peak on the DSC scan had no effect on the XRD trace, showing that the wide endotherm between 50-100° C. on DSC scan was due to the free solvent.

The Form 1 solid was heated in a DSC chamber to 305° C. (past the endotherm/exotherm around 280° C.), and then scanned by XRD. Comparison of the first and the third XRD and DSC scans shows that after heating to 305° C., Form 1 converted to Form 9. It can be concluded that the endotherm/exotherm around 280° C. might be due to melting/crystallization events.

Form 1 tended to convert to a non-stoichiometric or stoichiometric hydrate of Form 1 having between 1% and about 20% by weight water (Form 13) at RH above 4050%. The hydrate lost its water below 30% RH. Form 1 converts to Form 13 when exposed to air.

The dynamic vapor sorption (DVS) scan of Form 1 solid showed a 17% water absorption at 90% RH (FIG. 1D). The XRD data indicated that the solid used in the DVS test converted to the hydrate form before the start of the DVS test. However, at 0% RH, water was lost, perhaps indicating that the solid was Form 1.

The XRD peaks of Forms 2 and 2* are shown in Tables 9 and 10, below, respectively. DSC scans were also performed (FIGS. 2B, 2E, and 2H show the DSC scans of Forms 2, 2*, and 2**, respectively). According to the DSC scans, Forms 2, 2* and 2** each showed a wide endotherm between 50° C.-100° C., and multiple endotherms and exotherms before melting at 363° C. The wide endotherm before 100° C. may be due to the containment of water/solvent in the solid. Form 2 was obtained from acetonitrile; Form 2* from ethanol; Form 2** from n-propanol/5% water.

A TGA scan of Form 2 (FIG. 2C) showed a 2.7% weight loss before 116° C. FIG. 2F shows the TGA scan of Form 2*

A PLM photo of Form 2 was taken, indicating that the particle size of this solid was around 50 um.

The Form 2 solid was heated in a DSC machine to 90° C. (past the wide endotherm between 50-100° C.); to 270° C. (past the endotherm/exotherm around 240° C.); and finally to 330° C. (past the exotherm around 330° C.). The residual solid was analyzed by XRD. According to the first and second XRD and DSC scans, the form did not change before and after heating to 90° C. The wide endotherm between 50-100° C. might be free solvent or hydrate. According to the first and third XRD and DSC scans, after heating a Form 2 sample to 270° C., the solid converted to low crystalline solids. According to the first and fourth XRD and DSC scans, after heating the sample to 330° C., the solid converted to Form 9. Thus, the exotherm around 290° C. was a re-crystallization event. According to an XRD and DSC overlay, the behavior of Form 2* was similar to Form 2.

Residual acetonitrile and EtOH in Form 2 and 2* was not detected.

Additional experiments with Form 1 of a compound of Formula (I) showed that when Form 1 was exposed to moisture (FIGS. 15A-15D), Form 1 formed non-stoichiometric or stoichiometric hydrates. The crystal lattice of Form 1 expanded when water was sorbed, giving rise to XRD peaks at ˜5, ˜7 and ˜11 degrees while maintaining the main XRD pattern. The hydrates of Form 1 of a compound of Formula (I) (Form 11) were fully reversible, and lost water when exposed to % RH of less than 20%, turning Form 11 to hydrated forms of Form 1 and to the anhydrous Form 1.

M. Form 13 and Form 12

The experiments that generated Form 13 and Form 12 are shown in Tables 30 and 32, below, respectively. Forms 12 and 13 are examples of non-stoichiometric hydrates of Form 1 that have between 1% and about 20% by weight water. XRD scans of Form 13 and Form 12 were taken (FIGS. 13A and 12A, respectively). The XRD peaks of Form 13 are shown in Table 31, below. DSC scans of Form 13 and Form 12 were also taken (FIGS. 13B and 12B, respectively). According to the DSC scan, Form 13 solids showed a wide endotherm between 50° C.-100° C., followed by a small exotherm at 278° C.; and a melting endotherm at 363° C. According to the DSC scan, Form 12 solids showed a wide endotherm between 50° C.-100° C., followed by a sharp exotherm at 283° C.; and a melting endotherm at 364° C.

The purity of the Form 13 sample was 98.8%; the KF of an undried Form 13 sample was 35.7%. A DVS scan of Form 13 solid showed a 17% water sorption at 90% RH (FIG. 13D). Form 13 converted to Form 1 upon drying.

A TGA scan of Form 13 solid showed a 1.9% weight loss before 100° C. (FIG. 13C).

Form 13 solid was heated in a DSC chamber to 170° C. (past the endotherm between 50-100° C.), and then scanned by XRD. A comparison of the first and the second XRD and DSC scans, after heating to 170° C., showed that Form 13 converted to Form 1. It can be concluded that the endotherm between 50-100° C. is due to bonded water.

Form 13 has a primitive orthorhombic crystal structure with the approximate dimensions: a [Å]=33.759, b [Å]=22.590, c [Å]=7.386 and an approximate volume cell of [Å³/cell]=5,632.5 and a space group defined as Pbca(61).

Form 13 solid was heated in a DSC chamber to 330° C. (past the endotherm/exotherm around 300° C.), and then scanned by XRD. A comparison of the first and the third XRD and DSC scans, after heating to 170° C., showed that Form 13 converted to Form 9. It can be concluded that the endotherm/exotherm is due to melting/crystallization events.
